A very small population of a species faces a greater threat of extinction than a larger population. Provide a suitable genetic explanation.
A very small population of the species faces a greater extinction than the larger population because they face more random fluctuation which results in death of the individuals. They face random fluctuation through which individuals' mortality (death rate) rate is very high than the natality (birth rate) rate which ultimately leads to extinction of the lineage of the species or the small population. And the main reason for the small population extinction is inbreeding because when the species hybridize with the two different species will lead to decrease in the population’s potential and show harmful mutations. Smaller population shows fewer amounts of variations and face extinction because variation enables the organisms to face the struggle for existence in a better way.
